I know it is int, but I think this needs a redesign in C.

 I strongly encourage you not to do that.  Based on past
experience most of your ideas for improvements make
things worse rather than better.

It is only for static analysis.
For instance:
enum  E {Z = 0};
int main()
{
   int * p;
   p = '\0';
   p = false;
   p = Z;
}
clang has 3 warnings for this code.

Especially for p = Z and p = '\0' we have value 0 of type int, but the compiler is not blind for the other characteristics.
